Yes, the dream is that someone will somehow come up with something that works on amplifiers.But right now I'd be happy for something that worked on my phonostage! How hard can that be???Hell, I've gone so far as to take my pre-amp off the grid!...

[quote user="Paul S"]Romy, I am on the verge of an L-pad for my HF ribbons, but in my case I believe it is mostly the MC cartridge response I am wanting to offset, on a case by case basis. [/quote] Hm, this it VERY bad. Fix you cartridge setup, it's ...

How ironic that I finally got my phono running through the ML2s, and just as you say, it was not all it should be. In fact, I would have to say at this point that I am getting better sound from my crappy CD player, which I u...

and I hope it will be up to the level … of FM in term of enjoyments. Anyhow, the phonostage is the already pack up in the chassis and running. I dropped the B+ supply to 270V and the R1 restore to 120K, keeping the 100V on the first plate. I can’t wa...

[quote user="Romy the Cat"]That is a good question and I asked myself it numerous times. My current standing is the benefits are purely intellectual as I am not able to observe the applied benefits. [/quote] Recently I got eventually the box (th...

I am having a LOT of microphonic trouble with the 7788s in a high gain stage. I run a 40mV input signal into a 7788 triode at 15mA CCS. Plenty of gain, nicel output. But dang, if I bump the tube or board or chassis, the grids inside...

No, VTA is not in and of itself a characteristic of Sound; but in my own system the stylus' vertical tracking/rake angle is not something that results in the same sound no matter where I put it. In fact, even small chan...

[quote user="Romy the Cat"]I did not say how my saga with APS Pure Power regenerator finish but it never finished. Since the end of the last year the regenerators is sitting in my closet and I have sent the unit’s main board to APS people for the “re...

Last night local guy stopped by to listen my last year changed in Audio. I proudly played to him a record on my “End of the Life Phonostage”… it sounded like crap. The electricity was not very good and I hardly was toleration when the record was over...

Todd, What you descried does not sound to me as inner-groove distortion, even though I am not exactly sure what inner-groove distortions are. The very first questing that I would ask if you have the same character of sound when you play your CD, or t...

Alex,
I cannot answer your questions objectively. It was over 15
years ago when I was working with this phonostage and since I built the last
version, I did not make any experiments with it. I do feel the design is
spectacular, and I am lu...

that you specific PP is defective. If it is then all bets are off.

Completely agree. And I will say from the forum members here who have ...

[quote user="Paul S"]Romy, doesn't Tim de P also use this cool Miller capacitance idea in his never-mentioned "high end" tubed corrector? Also, do I remember reading that he runs both channels through the two halves of the same twin-triod...

Since the 2007-2008 alchemic music season and consequentially live FM season was over (the event I marked with my “End of the live Phonostage”) I have been spinning a lot of vinyl lately. So, I spent some time with different phono cables with my diff...

I was reading one commercial audio site where it was said: “….each MAS product is totally assembled and tested by one of our trained technicians who sign his name on the finished product. “ I wonder - why it is not a normal practice in high-end ...

I got home today, power up the payback and played some bootlegs of Australian festivals that Kostas Metaxas sent me another day. I paid attention that the sound was strange it was too hard atop. That was something new. I put in my player the CDs...

Got today a shipment from Tokyo with the OS-106 record. It is the same Ormandy’s Bach with Philadelphia but pressed but Japan. It sounds even better. To hear it today is even more fun than ever. We have very windy but very warm day today and the New ...

I made today a bunch of experiments with shielding of the MF filtering choke and I have very good progress. I was talking with different people and had a number of good advises (Come one, people the ward “advise” must have a plural form!) The in...

OK, folks, today I have started slowly to setup the playback itself. I took the small bass speaker I have and moved it around the room. The room surprisingly bassy, that is good. While I was doing it I was installing my TT, set up phonostage... I de...

Romy,I used second tube grid resistor, 1.8Meg Holco. (I couldn't find 2 Meg chip and good quality resistor: Dell RN60D or Holco or even Caddock MK-132.)But I felt the deep bus was cut. I tried 1.8Meg Holco & Riken 220K in serial. The deep bus inc...

[quote user="twogoodears"]Maybe someone read this http://twogoodears.blogspot.com/2009/05/we-437-based-phono-stage-solid-rock-did.html, worth reconsidering its design - also (partially) using WE 437A - after the last posts discussion at Roman's.....

"... and I do not know if 3A/167M is better than anything else and I do not see why the metal socket is necessarily better then plastic – the socket is not the part of the tube."As you know, the 437A is like an on-steroids ECC83, ALL glass built, no ...
